Vehicular lamp

ABSTRACT

The invention relates to a vehicular lamp, comprising a dome cap ( 1 ), a reflector mirror ( 2 ), a bulb ( 3 ), a protective shield ( 4 ), and a frame ( 5 ) for securing the protective shield. Inside the frame ( 5 ) is a resilient attachment ring ( 6 ), encircling the frame and supporting the protective shield ( 4 ) and the reflector mirror ( 2 ) as well as the bulb ( 3 ).

[0001] This invention relates to a vehicular lamp, comprising a dome cap, a reflector mirror, a bulb, a protective shield, and a frame for securing the protective shield.

[0002] For example, U.S. Pat. No. 5,491,619 describes a vehicular lamp of this type, wherein attempts have been made to dampen bulb vibrations by means of rubber plugs. There are a multitude of prior known anti-vibration solutions of this type. However, experiments and experience have shown that small rubber plugs, provided with an attachment head, are not sufficient for the dampening of bulb vibration. The dampening of a bulb requires a very large heavy mass, which remains stationary despite vibration. A vehicular lamp of the invention is characterized in that inside the frame is a resilient attachment ring encircling the frame and supporting the protective shield and the reflector mirror as well as the bulb. Thus, a major part of the entire lamp can be supported from the vibration dampening and resilient attachment ring. Tests have shown that this type of vehicular lamp of the novel invention provides up to a ten-fold saving for the bulb. Various embodiments of the invention are disclosed in the non-independent claims of the set of claims.

[0003] The invention will now be described by way of example with reference to the accompanying drawing, which shows a vehicular lamp in a partially cut-away view.

[0004] The lamp consists of a dome cap 1, a reflector mirror 2, a bulb 3, a protective shield 4, and a frame 5 for securing the protective shield. Inside the frame 5 is a resilient attachment ring 6, encircling the frame and supporting the protective shield and the reflector plate as well as the bulb. The attachment ring 6 is provided with support legs 7, extending in cross section towards the edges of the frame 5 and having therebetween an attachment groove 8 for retaining the protective shield and the reflective mirror. Between the support legs 7 and the attachment groove 8 are recesses 9 for more resilience to the attachment ring 6. Although the bulb need not be replaced often, the lamp is provided with quick-release buttons 10, which are located on the sides of the frame 5 and by means of which the frame and the components mounted on the frame are readily and quickly removable for a replacement of the bulb. 

1. A vehicular lamp, comprising a dome cap (1), a reflector mirror (2), a bulb (3), a protective shield (4), and a frame (5) for securing the protective shield, characterized in that inside the frame (5) is a resilient attachment ring (6), encircling the frame and supporting the protective shield (4) and the reflector mirror (2) as well as the bulb (3).
 2. A lamp as set forth in claim 1, characterized in that the attachment ring (6) is provided with support legs (7), extending in cross section towards the edges of the frame (5) and having therebetween an attachment groove (8) for retaining the protective shield and the reflective mirror.
 3. A lamp as set forth in claim 1 or 2, characterized in that between the support legs (7) and the attachment groove (8) are recesses (9) for more resilience to the attachment ring (6).
 4. A lamp as set forth in any of claims 1-3, characterized in that the frame (5) has its sides provided with quick-release buttons (10), by means of which the frame (5) and the frame-mounted components (2, 3, 4) are removable for a replacement of the bulb (3).
